ful Improvements in Machines for Tacking the Shoe Uppers and Counters, of which the following is a specification.

My invention relates to a shoe upper tacking machine.

The bjeot of my invention is to produce gather the surplus and loose' portions of the upper and counter' at the inner ends of a heel-seat adjacent to the ends of the welt, and push them in toward themedial line of the shoe and hold them there while they are tacked.

I itherto-,in making welt shoes, after the shoe came from the inseam stitcher and welt trimmer, that ortion of the heel-seat 'toward the shank o the slice was comparai tively loose. It was the custom to push the f the w-ould s material in as well as possible and insert and drive .a tack by hand. But with this method the 'open ends of the heel-seat j to theends of the welt were left so wide that read, making a wide heel-seat, an in the su sequent operation of trimming the edge ofthe o-utsole, the cutter would run into and sever the stitches at the shank of the last.

fully set forth in the description 'of the act `the welt by this means. The result is that cated by the bell' crank lever 4.

I have produced a machine to make the heel-seats narrow adjacent to the welt.

The features of the invention are more 1 represents the iframe of the machine, 2

lShafft 2 is provided with cam mechanism, t not shown), operating bell crank lever-4.

6 represents an arm in the' outerend of' which is supported a1 nail driver 'l' recipro- 8 represents a block for receiving the tacks and within whichthe driver reclprocates.

9 represents a* hopper forholding the tacks, and 10 a chute 'for delivei ug them to the block 8.

"11 represents a tack feed regulatir recip` l residing at Cinust adjacent `terial to be tightened.

rocated by means of an eccentric rod 12 operated from shaft 2. By means oi this mechanism, which is of well-known type, the tacks may be fed one at a time to the nail block 8 and the tack driven when the machine is put into operation by treadle and clutch mechanism, part of which is shown at 5, Fig. 1.

'13 represents a tucker, which is preferably a resilient blade attached at its inner end to the frame of the machine and having it-s outer end terminating immediately adja-` cent to the lower end oit the nailing block, as indicated in Fig. l. yllhe tucker is shown in Fign in plan view as adjustably longitudinally secured to the tableof the machine by the ordinary slot and bolt connection 20, 21.

The juxtaposition vof the nailing block and the tucker is such, (see Fig), that in order to present the heel-seat portion of the shoe to the tack driver, the edges of the upper and counter at. the convex portion ot the heel-scat of the last, must be eiigagedby the end of the tucker 13, so that when a shoe is pressed vin to' the nailingblock by the hand of the operator, thev surplus and loose material will be crowded in and l pushed toward the medial line of' the shoe.

`When the heel-seat has been made as narrow as practical on one side of the shoe, the tack is driven, the shoe is reversed and the heel-seat narrowed on the opposite side and secured by the tack. have found by actual measurement that can make the heel-seats an eighth. of an inch narrower adjacent to the upper and counter conform 'snugly to the shank of the last and a very narrow heet seat is formed, so that the shoe is .not only `better shaped, but in the subsequent opera-- tions the stitching is not damaged by the i sole trimmer. f

As will be seen from Fig. '3, the outer or 'workin'r end of the blade 1,3 is wide eiioii h to engage a substantial portion oi the ma- The end of the blade is thin, and as willbe readily understood by the the s oe to bc engaged 'between the welt and upper, in position to engage the adjacent stitches vin stretchii'ig i the upper in wardlyiover the last.

Having described myinventioinl'. claim v 'ft'.-fA machine for: gathering in and hold` dii iid

ordinary welt operator, lthe guXta 'ositlon of the blade and driver permit i ie -. ing the upper and counter` at the inner ends prismg stationary positioning means to en of the heel seats of a welt shoe while they are being tacked, consisting of a tacking device, and a resilient tucker blade, the free end of which lies under and immediately adjacent to the tack driver in position to.

push inwardly the material to be tacked as the shoe is presented by the hand of the operator, substantially as described.

2. A machine for gathering in and holding the upper and counter at the inner ends ot' the heel seats of a welt shoe while they arel being tacked, consistingof a tacking device, and a resilient tucker blade, the' inner end of which is supported by the frame of the machine, and the outer end of which lies under and immediately adjacent to the tack driver in position to push inwardly the material to be tackedfwhen the shoe is present` ed by the hand of the operator, substantially as described.

3. A machine of the class described, comprising a projecting arm secured to the ma chine and adjustable lengthwise, and tacking mechanism, the engaging end of said arm and the delivery point of 'said tacking mechanism approximately coinciding, said engaging end of the arm being imposition to permit a lasted shoe upper and welt to be pushed tberecver for stretching a loose portion of theuppcr tightly over a last in position to receive a tack from said tacking mechanislnwhile so held'stretched.

4. A machine for gathering in and holds ing the upper cfa lasted welt shoe at the inner ends of the heel seats while they are being tacked, consisting of'a tacking device, a frame, and a resilient arm -mounted on the frame, the free end ofsaid arm being in position to permit a lasted shoe upper and welt to be pushed thereover for stretching the upper over ay last in position to receive a tack from said tacking mechanism while so held stretched.

5. A machine of the class described, comgage the shoe between the welt and upper in position to press against the adjacent line of stitches and stretch the upper over the last and means for driving a tack to retain the upper While held thus stretched.

(3. A machine of the class described, eom prising a projecting arm secured to the machine, having a thin wide endvshaped and arranged to engage the upper beneath the Welt, and tacking mechanism including a nozzle, said engaging end of the armheing located immediately below and approximately inline with the tack delivering end of said nozzle.

A 7. A machine of the class described, comprising a positioning memberhaving an engaging end to enter beneath the welt to pressthe upper forward over thelast, said end being unyielding to forward pressure of the shoe and yielding to vertical pressure of the shoe, and tack-delivering means locatedapproximately in vertical alinement with the lextremity of said engaging end of said mem- -8. In a machine for working over a last the portion of shoe stock adjacent 'to the ends of the inseam, means for engaging the shoe in the welt crease to tighten the upper over theA last, said means being constructed and arranged for automatic movement upwardly under lengthwise pressure against it.

device located below the taclcdriving means and comprising a spring arm adapted to engage a welted shoe in4 the welt crease and constructed and arranged to lift the shoe toward the tracking means ,by the pressure applied in forcing the upper into the lasted position.

11. A machine of the class described,

having, in combination, a tacker, and meansV for workinginto lasted position the upper et' a welted shoe adjacent to the end of the inseam and the end of the row 'of heel seat tacks, said means being constructed and arranged to engage the shoe stock between'the upper and the welt a'nd force the upper inwardly over the edge of the last and upwardly toward the tacker and to hold the upper under tension while it is fastened by the tacker. l.

In testimony whereof, I have hereunto set my hand. y
